When creating a contour drawing, the following techniques should be used:
- Give yourself indications of where bits might be and then connect the dots.
- Keep your wrist relaxed.
The other options, such as drawing from memory after looking at the subject only once, and using an eraser liberally, do not align with the principles of contour drawing. Contour drawing often emphasizes looking at the subject while drawing to capture its outlines and details, rather than relying on memory, and it typically involves a more continuous line without frequent corrections.
